Omegasus

A play on words for Omega, and Sus.

Sus is derived from suspicious, popularized by the game Among Us.
Omega, despite omega being the last letter in the Greek alphabet, it is used as a synonym for Mega.

For one to be Omegasus, they must be beyond just sus. A person who is so suspicious that even their closest friends would be suspicious of them beyond the game, and would question their real-life loyalties.

*best used in chat's, it sounds cringe when spoken aloud.
